Check engine
Illuminates briefly to ensure the
system is functional. If it comes on
after the engine is started, one of
the engine's emission control
systems may be malfunctioning. The
light may illuminate without a driveability concern being noted and will
not require towing.
Light turns on solid:
Temporary malfunctions may cause your light to illuminate. Examples
are:
1. The vehicle has run out of fuel.
2. Poor fuel quality or water in the fuel.
3. The fuel cap may not have been properly installed and securely
tightened.
These temporary malfunctions can be corrected by filling the fuel tank
with high quality fuel of the recommended octane and/or properly
installing and securely tightening the fuel cap. After three driving cycles
without these or any other temporary malfunctions present, the light
should turn off. (A driving cycle consists of a cold engine startup
followed by mixed city/highway driving.) No additional vehicle service is
required.
If the light remains on, have your vehicle serviced at the first available
opportunity.
Light is blinking:
Engine misfire is occurring which could damage your catalytic converter.
You should drive in a moderate fashion (avoid heavy acceleration and
deceleration) and have your vehicle serviced at the first available
opportunity.
Under engine misfire conditions, excessive exhaust temperatures
could damage the catalytic converter, the fuel system, interior
floor coverings or other vehicle components, possibly causing a fire.

HOMELINKTUNIVERSAL TRANSCEIVER (IF EQUIPPED)
The HomeLinktUniversal Transceiver, located on the driver's visor,
provides a convenient way to replace up to three hand-held transmitters
with a single built-in device. This feature will learn the radio frequency
codes of most current transmitters to operate garage doors, entry gates,
security systems, entry door locks, and home or office lighting.
When programming your HomeLinktUniversal Transceiver, to a
garage door or gate be sure that people and objects are out of
the way to prevent potential harm or damage.
Do not use the HomeLinktUniversal Transceiver with any garage door
opener that lacks safety stop and reverse features as required by U.S.
federal safety standards (this includes any garage door opener model
manufactured before April 1, 1982). A garage door which cannot detect
an object, signaling the door to stop and reverse, does not meet current
U.S. federal safety standards. For more information on this matter, call
toll-free: 1±800±355±3515 or on the Internet atHomeLink.jci.com.
Programming
Do not program the HomeLinktUniversal Transceiver with the
vehicle parked in the garage.
1. Prepare for programming the
HomeLinktUniversal Transceiver by
erasing the three factory default
codes by holding down the two
outside buttons until the red light
begins to flash after 20 seconds.
Release both buttons.
2. Hold the end of your hand-held
transmitter 5±14 cm (2±5 inches)
away from the HomeLinktUniversal
Transceiver surface (located on your visor) while keeping the red light in
view.

Childproof door locks
When these locks are set, the rear
doors cannot be opened from the
inside. The rear doors can be
opened from the outside when the
doors are unlocked.
The childproof locks are located on
rear edge of each rear door and
must be set separately for each
door. Setting the lock for one door will not automatically set the lock for
both doors.
Move lock control up to engage the childproof lock. Move control down
to disengage childproof locks.
INTERIOR LUGGAGE COMPARTMENT RELEASE
Your vehicle is equipped with a mechanical interior luggage compartment
release handle that provides a means of escape for children and adults in
the event they become locked inside the luggage compartment.
Adults are advised to familiarize themselves with the operation and
location of the release handle.
To open the luggage compartment
door (lid) from the inside, pull the
illuminated ªTº shaped handle and
push up on the trunk lid. The
material that the handle is made of
will glow for hours in the darkness
of the luggage compartment
following brief exposure to ambient
light.
The ªTº shaped handle will be
located either on the luggage
compartment door (lid) or inside
the luggage compartment near the
tail lamps.

Keep vehicle doors and
luggage compartment
locked and keep keys out of a
child's reach. Unsupervised
children could lock themselves in
an open trunk and risk injury.
Children should be taught not to
play in vehicles.
On hot days, the temperature in the trunk or vehicle interior can
rise very quickly. Exposure of people or animals to these high
temperatures for even a short time can cause death or serious
heat-related injuries, including brain damage. Small children are
particularly at risk.
REMOTE ENTRY SYSTEM (IF EQUIPPED)
This device complies with part 15 of the FCC rules and with RS-210 of
Industry Canada. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and (2) This device
must accept any interference received, including interference that may
cause undesired operation.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to
operate the equipment.
The remote entry system allows you to lock or unlock all vehicle doors
without a key.
The remote entry features operate with the ignition in any position,
except in RUN, with the transmission not in either P (Park) or N
(Neutral).
If there is any potential remote keyless entry problem with your vehicle,
ensureALL key fobs(remote entry transmitters) are brought to the
dealership, to aid in troubleshooting.
